Specific embodiment
Describe in detail below in conjunction with the accompanying drawings：As illustrated, being connected and composed by change-over circuit and control circuit, change-over circuit pair
220V alternating voltages carry out step-down rectifier, and output DC12V voltages are supplied to control circuit, bright with bulb in controlling circuit
Go out.
Above-mentioned described change-over circuit by power transformer T, 4 commutation diode D1-D4, voltage stabilizing chip U7812,4
Electric capacity C1-C4 is connected and composed；The input of voltage stabilizing chip U7812 connects the positive output end of rectifier bridge, voltage stabilizing chip U7812's
Output end is+12V, electric capacity C1, the input of one end connection voltage stabilizing chip U7812 of electric capacity C2, electric capacity C1, electric capacity C2 it is another
End connection negative pole；Electric capacity C3, one end of electric capacity C4 connect the output end of voltage stabilizing chip U7812, electric capacity C3, the other end of electric capacity C4
Connection negative pole；AC energy is converted to direct current energy, is powered with to the relay in subsequent conditioning circuit.
Above-mentioned described control circuit is by the key normal open switch S1 that turns on light, the key normally closed switch S2 that turns off the light, with contact K1, K2
Relay J, illuminating lamp Z are connected and composed；One end connection 220V power supplys one end of illuminating lamp Z, the other end connection relay of illuminating lamp Z
One end of the contact K2 of device J, the other end of contact K2 connects the other end of 220V power supplys；Turn on light key normal open switch S1 one end connect
Output+12V the ends of voltage stabilizing chip U7812 are connect, one end of the coil of the other end connection relay J of the key normal open switch S1 that turns on light,
One end of contact K1, the output+12V ends of the other end connection voltage stabilizing chip U7812 of contact K1, the coil of relay J it is another
End connects the one end for the key normally closed switch S2 that turns off the light, the other end connection negative pole GND of the key normally closed switch S2 that turns off the light.
Above-mentioned described relay J is two-way, and one of them is used to connect 220V alternating current circuits, and another road is used for normally opened
Switch S1 is carried out " electric self-locking ", i.e. after normal open switch S1 disconnects, lamp is still connected with 220V civil powers.
In normal power supply, illuminating lamp Z is such as opened, need to artificially click to turn on light and key normal open switch S1 and unclamp.The switch
Moment closure is pressed, automatically reset Summer Solstice or the Winter Solstice normal off open state at once after hand release.Normal open switch S1 closure moments are being pressed, by normal
The circuit that switch S1, relay J, normally closed switch S2 are formed is in the conduction state, then relay J is triggered to be powered and starts work
Make, armature adhesive contact K1, K2 of relay J.Contact K1 close when, normal open switch S1 moment close after automatically reset to
Daily off-state, causes former turning circuit to disconnect；But new turning circuit is formed by contact K1, relay J, normally closed switch S2,
The sustainable power supply for ensureing relay J oneself.I.e. by clicking key normal open switch S1, trigger relay J work of turning on light, so that
Armature adhesive contact K2, realizes that illuminating lamp Z is opened.
In normal power supply, illuminating lamp Z is such as closed, need to artificially click to turn off the light and key normally closed switch S2 and unclamp.The switch
Moment disconnection is pressed, automatically reset Summer Solstice or the Winter Solstice normal closure state at once after hand release.Moment is disconnected normally closed switch S2 is pressed, by touching
The turning circuit that point K1, relay J coils, S2 normally closed switch are formed disconnects, then relay J coil blackouts can not work, relay
The armature of device J unclamps contact K1, K2, causes execution circuit to disconnect, and realizes that illuminating lamp Z is closed.Normally closed switch S2 automatically reset to
After day normal closure state, because contact K1, normal open switch S1 are also at daily off-state, then relay J still fails to be powered, it is impossible to
Work, it is impossible to which adhesive contact K2, illuminating lamp Z cannot still be opened.
When night powers off suddenly, no matter whether illuminating lamp Z is in opening, regardless of whether key of turning on light is clicked, relay
Device J is in electroless state, it is impossible to which be triggered work, then be unable to adhesive contact K1, K2, and contact K1, K2 are in off-state,
Illuminating lamp Z cannot be opened.
When next day early restores electricity, normal open switch S1 is in daily off-state, and contact K1 is also at off-state.Want
When illuminating lamp Z works, it is only necessary to click the key normal open switch S1 that turns on light, relay J is triggered.So just realize early
Morning people does not play the purpose that bed lamp does not work, it is achieved thereby that saving electric energy.
